Step 303: 273310 + 905 = 274215
Step 304: 274215 + 905 = 275120
Step 305: 275120 + 905 = 276025
Step 306: 276025 + 905 = 276930
Step 307: 276930 + 905 = 277835
Step 308: 277835 + 905 = 278740
Step 309: 278740 + 905 = 279645
Step 310: 279645 + 905 = 280550
Step 311: 280550 + 905 = 281455
Step 312: 281455 + 905 = 282360

So, 905*312 = 282360
